Which airspace class allows IFR and VFR with clearance?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (C)

In this airspace, you have ATC supervision for both IFR and VFR traffic, with entry conditioned on communicating with ATC and receiving the appropriate clearance. IFR flights are given an explicit clearance to enter and operate under ATC separation, while VFR flights operate under ATC guidance once two-way radio communication is established and they comply with ATC instructions. This combination—both flight rules allowed and a requirement to be in contact with ATC before entry—defines the class around busy airports equipped with approach control. Other classes either restrict VFR, or handle entry and separation differently, so this configuration best matches the described scenario.
